Title:

FLOATING WIND TURBINE

Document Type and Number:

WIPO Patent Application WO/2011/056425

Kind Code:

A3

Abstract:

A bearingless floating wind turbine has a tall narrow main support structure with a center of buoyancy located well above the center of gravity to provide stability to the wind turbine while supported for rotation in a body of water, a vertical axis turbine blade extends from the main support structure and rotates together under a wind, and a non-rotating shaft extends through the main support structure with a vertical axis direct drive generator connected between the main support structure and the non-rotating shaft to produce electricity when the main support structure rotates. An anchor line connected to the non-rotating shaft prevents the floating wind turbine from drifting in a body of water.
